before i tear up my motors, i have the following doubts.
1) i m quite pleased with the speed/torque even with the regulator inside.
but only when i apply the power supply to it but not when i drive it thru
the ba6209 IC. i doubt whether the bloodshed
would do the trick.
2) when reverse biased, the inbuilt regulator gets bypassed automaticaly.
in that case the motor gives slightly more power but still not enuff.
(i.e when driving thru the ba... )
3) wont soldering the wires directly to the motor terminals (i.e bypassing
the regulator) spoil the regulator as this method would power up the
regulator too but from the wrong place ? is there a way to do this
peacefully ? i.e bypassing it but still letting the tiny reg. pcb live there
physicaly since it provides mechanical support to the motor's back lid ?
4) :lol: i knew the ohms law bogdanfirst. what i meant by the voltage and
current story was that to b able to draw more current (~ 400 mA per
motor), wont i need a power supply with that capability ?
or is the power supply i m using (i.e. wall adaptor 12V 500mA) enuff ?
i measured the current that way to know the max current drawable from the ba... and wasnt that supposed to be ~1.6A ?
i also measured the current the motor draws when stalled( :twisted: crazy again ?) and it read some 0.4 Amps.
i m in the process of drawing the schematic (still in the proc of getting used to Eagle). will b done in a few hrs. thx kinjal for that link
what would be the current capability of a battery pack of eight AA (UM-3) size cells ? better or worse.
thx again for taking interest and bearing me
Shima.
